Is this the total for code, data, bss, heap, etc?  Or do you have some 
Flash/Rom for code space?

The code space for an application with TCP/IP is usually over 128K.  I 
recall 256K being the
ballpark number on a 68k.

Most certainly, yes.  It is designed for lower memory footprints.

There are others including http://dunkels.com/adam/uip/.  I don't know 
which would be the best to
port.
